摘要
Di Crescenzo和Longobardi(2002)引入了过去熵，Sunoj等人(2013)给出了过去熵的分位数版本，称为过去分位数熵(PQE)。在PQE函数的基础上，他们定义了一种新的随机阶，称为少PQE (LPQE)阶，并研究了该阶的一些性质。在本文中，我们关注于这一新阶的进一步闭包性质。研究了LPQE阶的一些性质，得到了闭包和反闭包性质。讨论了比例故障率和反向故障率模型中LPQE顺序的保持问题。
Further results on closure properties of LPQE order
Di Crescenzo and Longobardi (2002) introduced the past entropy, Sunoj et al. (2013) gave a quantile version for the past entropy, termed as the past quantile entropy (PQE). Based on the PQE function, they defined a new stochastic order called as less PQE (LPQE) order and studied some properties of this order. In the present paper, we focus our interests on further closure properties of this new order. Some characterizations of the LPQE order are investigated, closure and reversed closure properties are obtained. The preservation of the LPQE order in the proportional failure rate and reversed failure rate models is discussed.
期刊介绍：
Statistical Methodology aims to publish articles of high quality reflecting the varied facets of contemporary statistical theory as well as of significant applications. In addition to helping to stimulate research, the journal intends to bring about interactions among statisticians and scientists in other disciplines broadly interested in statistical methodology. The journal focuses on traditional areas such as statistical inference, multivariate analysis, design of experiments, sampling theory, regression analysis, re-sampling methods, time series, nonparametric statistics, etc., and also gives special emphasis to established as well as emerging applied areas.
